ShellyPy.error.NotFound: Not Found even if Shelly 1 is reachable

I'm trying to using the library which should be pretty simple. I've used `device = ShellyPy.Shelly("xx.xx.xx.xx")` and with `device.update()` I can see the device name printing `print(device)`

Now, if I use
```
deviceMeter = device.meter(0)
print(deviceMeter['total'])
```
I've the error above

The thing is that I can correctly reach the IP from the same PC I'm trying to connect with Python.

Also, I don't know if I have to active `Allow Cross-Origin Resource Sharing ` on the Shelly?

Start with the ShellyPy.Shelly entry point and trace the requests made by update() and meter(0). Reproduce the Not Found response against the reachable Shelly 1, checking whether the requested endpoint and CORS expectations match the device. Done means the cause is identified and meter(0) behaves correctly or the limitation is documented.
